the average power output of the primary coil of microwave oven transformers (MOTs) is typically around 800 to 1200 watts. However, it's important to note that transformer designs and specifications may vary depending on the specific make and model of the microwave oven.
MOTs are commonly salvaged and repurposed by hobbyists and DIY enthusiasts for various high-voltage and high-current projects, such as creating high-voltage power supplies or induction heaters. When repurposing or using microwave oven transformers for any non-standard applications, extreme caution must be exercised due to the potentially lethal voltages and currents they can produce. Working with high-voltage electronics requires expertise and safety precautions to avoid serious injuries or fatalities.
For the most accurate and up-to-date information, I recommend checking the specifications of a particular microwave oven transformer or referring to reliable sources from manufacturers or experts in the field.
